IMPROVEMENT lN REFRIGERATORS.

Specification forming part of Letters Patent No. 222,924, dated December23, 1879; application filed October 31, 1879.

To all whom it may concern:

Be it known that I, SILA s W. LOLLER, of Cameron, in the county ofMarshall and State of West Virginia, have invented certain new anduseful Improvements in Boxes for the Transportation of Butter; and I dohereby declare the following to be a full, clear, and exact descriptionof theinvention, such as will enable others skilled in the art to whichit pertains to make and use it, reference being had shaped as tosurround the trays or wooden frame holding the butter, and thus preventheat from affecting the butter during transportation or storage, as willbe more fully described hereinafter.

Figures 1 and 2 are vertical sections of my invention, taken at rightangles to each other, showing the summer-trays. Fig. 3 is a plan viewofthe zinc framein which the ice is placed for summer use. Fig. 4 isavertical section of the box, showing the shelves used during coldweather.

it represents a suitable box or frame, in which the butter is to betransported and then set up in the merchants store, to keep the butteruntil sold.

During all the months of the year except the very hottest ones the traysc are used in the frame, which frame is provided with the grooves d toreceive them. Each tray is divided into a number of sections, which arejust large enough to hold a print or roll of butter, and each tray canbe drawn out so as to display the butter to the purchaser. With thesetrays 0 is used a door that is large enough to cover the whole side ofthe frame, so as to keep the heat from affecting the butter.

During the three or four hottest months of summer ice or water isabsolutely necessary to keep the butter hard, both while sitting in thestore ready for sale and during transportation. When ice is to be usedthe trays c are taken out, the door entirely removed, and then the Izinc frame 6, in which the ice is placed, is inserted. Fitting in thisframe 6 is a wooden frame, 9, which has grooves'out in its inner sidesto receive the trays i, and which wooden frame has secured to its outerend a portion of the end of the frame a and the door h.

The zinc frame is divided, by means of the openings in it for theflanges lot the frame g to fit in, into the chamber at, which extendsdown the back of the box, the two chambers 0, which extend over andunder the shelves, and the two chambers T, which extend along the sidesof the shelves or trays. The ice is introduced into this zinc framethrough the narrow door 8, made along the top edge of the frame a, andfrom the chamber a, into which the ice is dropped, it can be pushed intoall of the others by means of a stick.

The flanges l or projecting ends of the frame 9 rest against the innersides of the top and bottom parts of the frame a, as shown in Fig. 2,and into these flanges may be passed screws for the purpose of holdingthe frame in place. The frame is also held in place by means of theparts 0, which are secured thereto and form a part of the end of theframe a.

The tops of the trays i are covered with zinc, so as to be always kepteasily cleaned.

It will be understood that in some cases airinlet and air-outletopenings may be made to communicate with the cooling-chamber andpreserving'chamber and external air, whereby a free circulation of coolair may be caused to pass through the preserving-chamber.

Heretofore refrigerators have been made in which a chamber provided withshelves is shown surrounded with a chamber to receive water or ice, andthis is here disclaimed.

Having thus described my invention, I

claim- The metallic frame 6, divided into the chambers n o r, incombination with the frame 9, having the trays z, and theinclosing-frame a, having the door 8, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this17th day of October, 1879.
